The evaporation rate of the n-Hexane is 
<u>Explanation</u>:
This is a situation regarding diffusing A through non-diffusing B.
A = n-Hexane B=Air
Where the molar flux is provided by,



the vapor pressure at hexane

For wind, assume negligible hexane is present, hence 
Now,







where T = 298 K
substituting all in the equation, we get


Now,Flux
area = Molar rate of evaporation
Evaporation rate = 
Evaporation rate =

Explanation:
When testing a spring break it is advisable to Step on and off the brake, with the engine off, the parking brake knob is expected to pop out when air pressure falls between 20-40 psi.
Go under the vehicle and pull the spring brakes.
Turn on the engine back and pump the brake pedal down to the floor. To test the spring breaks
